Close Alternative — 76.2% match
based on chemical composition and mechanical property overlap.
GB/T 1222 55CrMnA (GB/T 1222-2016) and IS 3195 60Cr4V2 (IS 3195:1992) are both steel grades.
Both fall under the Spring Steel category.
GB/T 1222 55CrMnA is typically used for automotive leaf springs, coil springs, while IS 3195 60Cr4V2 is commonly used for volute and helical springs for railway rolling stock; flats and rounds, springs worked hot and heat-treated (clause 1.1, foreword).
GB/T 1222 55CrMnA is defined under Guobiao Standards (GB/T), originating from China, while IS 3195 60Cr4V2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, GB/T 1222 55CrMnA vs IS 3195 60Cr4V2 is a 76.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 76.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
